With general relativity, things really start to get interesting. ( To study aging, scientist are looking to outer space.) But I’ve travelled into my twin’s future.” “I’m no further into my future than normal. My clocks tick at the normal rate, I age normally, movies run at the right pace,” says Levin. “My experience of the passage of time is utterly normal for me. When you come back, you look just a few years older than when you left, while your twin is perhaps now a grandparent. Maybe you were both in your 20s when the voyage began. Interestingly, time appears to pass just as it always does for both twins it’s only when they’re reunited that the difference reveals itself. “It is absolutely provable in special relativity that the astronaut who makes the journey, if they travel at very nearly the speed of light, will be much younger than their twin when they come back,” says Janna Levin, a physicist at Barnard College in New York. It’s counterintuitive, to say the least, but the physics, after more than a century, is rock solid. When you come back home, you’ll find you’re now much younger than your twin. Suppose you head off to the Alpha Centauri star system in your spaceship at a really high speed (something close to the speed of light), while your twin remains on Earth. In fact, thanks to special relativity, you can end up with two twins having different ages, the famous “twin paradox.” Special relativity doesn’t give us a way of going back in time, but it does give us a way of going forward-and at a rate that you can actually control. “So maybe everything we can do with space, we can do with time.” The theory “establishes that time is much more similar to space than we had previously thought,” says Clifford Johnson, a physicist at the University of Southern California. General relativity renders gravity in a new light: Instead of thinking of it as a force, general relativity describes gravity as a bending or warping of space-time.īut special relativity is enough to get us started in terms of moving through time. Then, in 1915, Einstein came up with the second part of his theory, known as general relativity.

In it, space and time are malleable measurements of both space and time depend on the relative speed of the person doing the measuring.Ī few years later, the German mathematician Hermann Minkowski showed that, in Einstein’s theory, space and time could be thought of as two aspects of a single four-dimensional entity known as space-time. In 1905, Albert Einstein published the first part of his relativity theory, known as special relativity. Wells was a novelist, not a physicist, but physics would soon catch up. ( Why are people obsessed with time travel? Best-selling author James Gleick has some ideas.) Dueling theories “From there, it’s a short step to time machines.” “In space, you can go wherever you want, so maybe in time you can similarly go anywhere you want,” says Nikk Effingham, a philosopher at the University of Birmingham in the United Kingdom. We can move easily enough through space, so why not time?

What really kick-started scientific investigations into time travel was the notion, dating to the closing years of the 19th century, that time could be envisioned as a dimension, just like space. Wells penned his groundbreaking novel, The Time Machine, in 1895, and it’s something that physicists and philosophers have been writing serious papers about for almost a century. Time travel has been a fantasy for at least 125 years.

What if you could zip through time at will, travelling forward to the future or backward to the past as easily as pushing buttons on the dashboard of a souped-up DeLorean, just like in the movie Back to the Future?

But what about travelling through time? And not just the boring way, where we wait for the future to arrive one second at a time.

Jetting off to some fun-filled destination like we used to might not be in the cards for a little while yet. I’m stuck at home, you’re stuck at home, we’re all stuck at home.
